Title: Improvements in thermostatic control of carburetting devices for internal combustion engines
IPC: F02M23/10
Filed: 1935-03-16
Abstract: 438,319. Spray carburetters. SOC. GENERALE DES CARBURATEURS ZENITH, 10, Rue Petitot Geneva, Switzerland. March 16, 1935, No. 8252. Convention date, March 16, 1934. [Class 7 (iii)] In a carburetter having a main air inlet, an auxiliary air inlet and an auxiliary starting device which includes a mixing chamber communicating with the induction pipe, a single thermostatic element operates successively to close an outlet valve on the starting device and open an inlet valve for the auxiliary air as the temperature increases. The nozzle 30 of a starting device 31 supplies fuel, emulsified by air entering a port 32, to a chamber 27 communicating with the induction pipe 1, adjacent the throttle valve 2, through a port 28. This port is controlled by a valve 29 secured to a heat expansible element 37, dilation of which closes the valve and then opens a secondary air valve 35 communicating by a passage 36 with a space (not shown), in the mixing chamber of the carburetter between a Venturi 3 and the walls of the chamber. As shown in Fig. 4, the starting device supplies a chamber 80 in which a spring-pressed valve 74 is adapted to close a passage 50 to the induction pipe when a container 86 is expanded by the heat of the engine. The container is mounted in a sleeve 82 slidable in a casing 70 and carrying a valve 90. As the container continues to expand, the valve 90 is opened admitting air to the casing 70 and secondary air passage 63. A spring 84 engages a flange 83 on the sleeve 82 to return it to its position of rest and close the valve 90. The Specification as open to inspection under Sect. 91 describes a thermostatic element mounted on either the exhaust pipe or the carburetter for controlling the extra air inlet and another form in which an element on the carburetter controls the inlet of air for emulsifying the fuel. This subject-matter does not appear in the Specification as accepted.

Filed: 1962-03-05
Abstract: 972,474. Fuelling reactors. FAIREY ENGINEERING Ltd. June 5,1963 [March 5, 19621, No. 8403/62. Heading G6C. In order to prevent blow out of the fuel elements remaining in a reactor core channel after the majority of the elements in that charnel have been removed by a grab, the upward flow of coolant gas through the channel is automatically reduced by a valve responsive to the gas temperature. The valve is mounted at the lower end of a charge shoot adapted for connection to the channel and controls the flow from the channel into the space enclosed by the pressure vessel. At the normal working temperature of the gas in the channel corresponding to a fully loaded channel the valve is fully open but it closes progressively as the temperature drops as the fuel elements are removed. As shown, the lower end of a charge shoot 13 has a tubular extension 10 provided with ports 27 and surrounded by a fixed sleeve 15 having ports 25. Three annular members 20, 23, 24 are secured to the sleeve 15 and each annular member has four arcuate bimetallic strips 30 anchored thereto by rivets 32. The other ends of the strips 30 of each group are riveted at 33 to a ring 28 of L-section. At the normal working temperature of the gas the strips 30 are deflected so that the rings 28 are raised as seen in the right-hand half of Fig. 1 and the ports 25 are not obstructed. On cooling of the gas, however, the strips unflex so that the rings 28 drop and substantially close the ports 25 as shown in the left hand half of Fig. 1

Filed: 1936-03-23
Abstract: 474,081. Chain gearing. DINGLE, H., and McMAHONS, Ltd. March 23, 1936, No. 8610. [Class 80 (i)] [Also in Groups VII, XVI, and XXX] In an automatic work-feeding mechanism for machines for stapling books and the like, a chain-and-sprocket drive is adapted to impart intermittent movement to the conveyer chain 3. The sprocket 5 of the conveyer is driven by a chain 52 from a sprocket, not shown, on a shaft 50 carrying a sprocket 26 which, in turn, is driven by a chain 25 from a sprocket 20 on the main shaft 21 of the stapler head. The chain 25 is longer than would normally be necessary, and the slack is taken up by rollers 28, 29 mounted adjustably on the vertical arm of a bell-crank lever 32, the horizontal arm of which is pivoted at 33 to a rod 34 which is connected at its other end to a crank 38 on the shaft 21. As the shaft 21 rotates and drives the sprocket 26, the lever 32 is oscillated so that the slack of the chain 25 is transferred from one side to the other of the sprocket 26. Assuming the sprocket to be rotating clockwise, transference of the slack to its left side increases its speed of rotation, whilst transference to its right side brings it to rest. The mechanism is so adjusted that this rest period coincides with that period of the rotation of the shaft 21 during which a staple is driven. The sprocket 26, and the companion sprocket on the shaft 50 which drives the chain 52, are mounted adjustably on the shaft 50, as by a pin 58 engaging any one of a series of holes 57.

Abstract: 250,241. I. G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister, Lucius, & Br³ning). April 1, 1925, [Convention date]. Sulphonic acids.-Nucleur-alkylated or -cycloalkylated arylsulphonic acids are prepared by treating an aromatic hydrocarbon simultaneously with a higher aliphatic or alicyclic alcohol in the presence of chlorsulphonic acid. By the use of chlorsulphonic acid as the condensing-agent instead of sulphuric acid, the reaction can be carried out in a single stage, and the condensing- agent need not be used in excess; and considerably lower temperatures may be employed, so giving a superior product of light colour. In examples, to a mixture of naphthalene and n-butyl alcohol at 80-100‹ C., of naphthalene and cyclohexanol at 60-70‹ C., chlorsulphonic acid is added drop by drop, the solution may be used directly, or a solid product may be obtained by neutralizing into caustic soda or ammonia and subsequently drying. Anthracene or other aromatic hydrocarbon mav be used instead of naphthalene, and for butyl alcohol or cyclohexanol may be substituted isopropyl alcohol, commercial fusel oil or other aliphatic or alicyclic alcohol. The products obtained are wetting agents. Specification 242,233, [Class 15 (ii), Dyeing, Processes &c. for], is referred to.

[Classes 50 and 55 (i)] A dense turbulent mass of finely divided carbonaceous solid material fluidized by upwardly flowing gas is oxidized at temperatures e.g. of 150-650‹ F., lower than-that at which substantial carbonization occurs for a time sufficient to absorb 0.5-40 per cent of oxygen ; the process may be applied to strongly coking coals to reduce their agglutinating tendency during carbonization or gasification. Highly volatile bituminous coal, or lignite, oil shale, tar sands, asphalt, cellulosic material, &c. is ground in a pulverizer 3 and fed to an oxidizing chamber 15 through a standpipe 9 aerated by air stream, &c. introduced through one or more inlets 11. Fluidizing gas of oxygen content suitable for the process is supplied by a blower 23 through a pipe 17 and may be supplemented by recirculated gases after passage through a dust separator 54. A heater 60 and humidifier 62 may be included in the circuit. Oxidized coal is removed through a wall 30 and standpipe 32 to a carbonizing or gasifying chamber 50. A side stream may be returned to the chamber through a cooler 45. A number of superposed fluidized beds may be maintained in the oxidizing chamber or the bed may contain packing bodies or vertical baffles.

Title: Improvements in or relating to Moulds for use in the Construction of Vessels, Pontoons, or other Floating Structures, in Reinforced Concrete.
IPC: B63B9/06
Filed: 1918-05-27
Abstract: 127,389. Gueritte, T. A. J., and Mouchel & Partners, L. G. May 27, 1918. Boat accessories.-Vessels, pontoons, and ether floating structures constructed of reinforced concrete or similar material are moulded in moulds which are adapted to be used over again, and the vessel is removed from the mould bv water which is admitted or forced between the vessel and the mould. The vessel a, Fig. 1, is built in the mould b, which is of concrete, masonry, or brick, backed by soil c, and provided with gates to admit water and to release the vessel when floated. The mould may be made of a length, breadth and depth suitable for the largest ship contemplated to be built, and the parallel walls may be used for smaller ships, with temporary structures for the bow and stern ; in the case of still smaller ships, only one side wall f, f, Fig. VI, may be used, and the temporary shuttering g<2>, g<2> may be strutted from the fixed wall p, p. In a modification, the mould may be constructed in the form of a floating dock s. Fig. VIII, the walls w of the mould being separately formed and supported from the dock by struts x and blocks v. Alternatively, the inner surface of the dock wall may be shaped so as to act as the mould itself. In another modification, the temporary bow and stern portions of the mould mentioned above may be dispensed with by constructing it as a floating dock in two or more sections which are connected together as required. In order to detach the vessel from the mould, the latter may be covered by thick paper or textile material, to enable the water to reach every part of the surface. The detachment may be facilitated by providing a network of grooves in the surface of the mould, intersecting at rightangles, and of the form shown in 5, Fig. XII. The grooves are covered by slabs 4, of wood, iron, slate, cardboard or the like and all the grooves may be connected to conduits below the surface, to which the water is admitted, if necessary under pressure. When the mould is constructed of concrete or the like, blocks of wood, cokebreeze concrete, or the like are sunk into Its surface to provide means for the temporary attachment of the reinforcement by nailing. When constructing reinforced concrete floating docks. pontoons, caissons, or the like, a permanent mould bottom only is provided on the shore, the water being excluded by a temporary dam. In a modification, the platform may be constructed of bricks spaced apart to provide the channels for the admission of water, or of loose gravel or ashes having perforated water-supply pipes embedded in it.
